  Velocity \Ve*loc"i*ty\, n.; pl. Velocities. [L. velocitas,
     from velox, -ocis, swift, quick; perhaps akin to volare to
     fly (see Volatile): cf. F. v['e]locit['e].]
     [1913 Webster]
     1. Quickness of motion; swiftness; speed; celerity; rapidity;
        as, the velocity of wind; the velocity of a planet or
        comet in its orbit or course; the velocity of a cannon
        ball; the velocity of light.
        [1913 Webster]
  
     Note: In such phrases, velocity is more generally used than
           celerity. We apply celerity to animals; as, a horse or
           an ostrich runs with celerity; but bodies moving in the
           air or in ethereal space move with greater or less
           velocity, not celerity. This usage is arbitrary, and
           perhaps not universal.
           [1913 Webster]
  
     2. (Mech.) Rate of motion; the relation of motion to time,
        measured by the number of units of space passed over by a
        moving body or point in a unit of time, usually the number
        of feet passed over in a second. See the Note under
        Speed.
        [1913 Webster]
  
     Angular velocity. See under Angular.
  
     Initial velocity, the velocity of a moving body at
        starting; especially, the velocity of a projectile as it
        leaves the mouth of a firearm from which it is discharged.
        
  
     Relative velocity, the velocity with which a body
        approaches or recedes from another body, whether both are
        moving or only one.
  
     Uniform velocity, velocity in which the same number of
        units of space are described in each successive unit of
        time.
  
     Variable velocity, velocity in which the space described
        varies from instant to instant, either increasing or
        decreasing; -- in the former case called accelerated
        velocity, in the latter, retarded velocity; the
        acceleration or retardation itself being also either
        uniform or variable.
  
     Virtual velocity. See under Virtual.
        [1913 Webster]
  
     Note: In variable velocity, the velocity, strictly, at any
           given instant, is the rate of motion at that instant,
           and is expressed by the units of space, which, if the
           velocity at that instant were continued uniform during
           a unit of time, would be described in the unit of time;
           thus, the velocity of a falling body at a given instant
           is the number of feet which, if the motion which the
           body has at that instant were continued uniformly for
           one second, it would pass through in the second. The
           scientific sense of velocity differs from the popular
           sense in being applied to all rates of motion, however
           slow, while the latter implies more or less rapidity or
           quickness of motion.
           [1913 Webster]
  
     Syn: Swiftness; celerity; rapidity; fleetness; speed.
          [1913 Webster]
